Choose the wrong statement

Options

A. Unit of force is newton
B. Force changes shape of body
C. Force is always conserved
D. Force is vector quantity.

Explanation

To solve the question of identifying the wrong statement among the given options, we will analyze each statement one by one.

**Step 1: Analyze the first statement.**
- The first statement claims that "the unit of force is Newton."
- We know that the unit of force in the International System of Units (SI) is indeed Newton (N). Therefore, this statement is correct.

**Step 2: Analyze the second statement.**
- The second statement states that "force changes the shape of a body."
- It is true that when a force is applied to an object, it can cause deformation or change in shape, even if that change is very small. Thus, this statement is also correct.

**Step 3: Analyze the third statement.**
- The third statement says that "force is always conserved."
- This statement is incorrect. Forces are not conserved quantities; they can change depending on the circumstances and the application of different forces. Therefore, this statement is wrong.

**Step 4: Analyze the fourth statement.**
- The fourth statement claims that "force is a vector quantity."
- This statement is correct because force has both magnitude and direction, which is characteristic of vector quantities.

**Conclusion:**
After analyzing all four statements, we find that the third statement is the only one that is incorrect.

Thus, the wrong statement is: **"Force is always conserved."**
